This obnoxious little bugger is the Idle Air Control Valve off of a Honda Civic. Specifically it is the same model part that comes off of my Honda Civic. Ever since I swapped engines in my Civic three or four months ago this part has not worked right. I had no idle air control so when the car was cold it would idle too low (300-400RPM) and when I turned on the A/C the car wouldn’t idle correctly at all (nearly die, turn off the compressor, rev back up to 800, compressor switches on, car nearly dies, repeat). I tried every fix I could find: swapped valves with another car, cleaned the valve, bled my coolant system multiple times, played with ALL of the idle adjustment screws. Nothing worked. Yesterday I finally took the valve itself apart. It’s basically a chunk of metal with a shutter inside with a permanent magnet on the end of the shaft, with a completely sealed plastic controller (the black part) that screws on the end and has electromagnets in it, making the whole thing a brushless motor with 90-ish degrees of rotation. I moved the shutter back and forth a few times until the movement was much smoother and free of grit, then popped it back on the car. Voila, I now have A/C. Furthermore, I have an incredibly good A/C since the Canadian Civic didn’t come with A/C standard so this unit was several years younger than the car. It’s silly cold and I love it. Car is a lot happier now, too.

Nice job! Bad IACs are typically not much fun. It will be interesting to see how long your fix lasts, though. Its possible it gets stuck again after a little while.

When the IAC was failing in my crown vic, the made a sound like a goose playing a french horn at idle, that alone was enough to get me to replace it (not to mention the really high idle in gear)
